| SteveM | 23-Mar-10 20:55 | | The upper right wing on the plans is not to scale as you can see by this 3/32" gap at the end of the ailerion T.E. (Part A9) |
| SteveM | 23-Mar-10 20:58 | | I measured the upper left wing to be 19 3/32", the upper right to be 19 3/16", the lower left is 19" and the lower right is 19 5/32" when measuring the length of the wing along the main spar. Based on the fit of the parts I'd say 19" would be the correct dimension and the others were stretched in printing. I've never noticed this kind of slop before, is this fairly normal? |
| David Duckett | 24-Mar-10 07:09 | | I don't know about normal but it's just one of several things about this kit that are not quite right. Although noted, I normally just build around whatever is wrong since often it's a matter of "the written word" and I'm used to dealing with bad grammar and spelling. There's an error regarding the ribs R3A and R4A on the bottom wing. The instructions say to glue them to the trailing edge but the ribs aren't made that way as they fit on top of the bottom sheeting and don't go all the way to the trailing edge. The plans show the ribs all the ways and that's not right. The plans are also wrong regarding the aluminum tubes that fit in the wings...the bottom wing shows them flush with the root rib but the top wing shows them extending past it. If the wings are built to be removeable the tube should be flush because it fits over another aluminum tube in the fuselage. The length of the wing tubes per instructions doesn't match the plans, either. |
| SteveM | 24-Mar-10 13:25 | | Thanks for the heads up on the errors, I'll make notes of them when I got home tonight. I too find issues with vague wording that could have been made crystal clear with just an extra word or two. For example, the Ambroid glue directions leave me in doubt as to whether the glue should be applied to one side of the joint or both. I don't recall the exact wording off the top of my head.
When I get home I'll measure the larger Guillow's plans for accuracy and see if it is common to their plans too. Since you have the same problem then there is no point in getting new plans from Dumas as those would just be stretched too. If I wasn't building to fly I'd just make it all fit and not sweat it. |
| jgood | 24-Mar-10 14:53 | | Steve. I had a similar problem with my Tiger Moth plans I think too. Also my Molt P-38. Here's the discussion about that. The consensus was it was probably caused by the duplication process, not paper itself. I'll check mine when I get it out of storage... |
